Cruz, in an apparent act of desperation, announced Wednesday that Carly Fiorina will be his vice presidential running mate if he is the Republican nominee for president. Announcing a running mate is an unusual step that comes as he trails GOP front-runner Donald Trump by a wide margin and faces an increasingly narrow path to the Republican nomination.

“Cruz has no path to victory – he is only trying to stay relevant,” Trump said in a statement Wednesday. “… Senator Cruz has millions of votes less than me and is being clobbered on the delegate front, this is a pure waste of time.”

The announcement follows Trump’s five-state sweep Tuesday, in which he declared himself the party’s presumptive nominee. Cruz won only three delegates Tuesday night.
